what is mokume gane

Mokume-gane is a Japanese metalworking procedure which produces a mixed-metal laminate with distinctive layered patterns; the term is also used to refer to the resulting laminate itself. The term mokume-gane translates closely to "wood grain metal" or "wood eye metal" and describes the way metal takes on the appearance of natural wood grain. Mokume-gane fuses several layers of differently coloured precious metals together to form a sandwich of alloys called a "billet." The billet is then manipulated in such a way that a pattern resembling wood grain emerges over its surface. First developed in 17th-century Japan, mokume-gane was originally used for swords. As the customary Japanese sword stopped serving as a weapon and became largely a status symbol, a demand arose for elaborate decorative handles and sheaths. Mokume-gane is now used to create a variety of objects, including jewelry, knife handles, and decorative panels. The technique is relatively complex and time-consuming, but it can produce stunning results.
